MACHINE FOR SHARPENING HORSESHOE-CALKS SPEGIFICATL IIQNfor ming part of Letters Patent No. 659,388, dated October 9, 1900.

, Application filed May 28. 1900.

To all whom, it may concern:

, Be it known that I, PETER B. BRAZEL, a citizen of theUnited States, residing at Cheboygan, county of Cheboygan, State of Michi: gan, have invented a certain new and useful Improvement in Machines for Sharpening Shoe-Calks; and I declare the followingto be afull, clear, and exact description of the same, such as will' enable others skilled'in the art to which it pertains to make and use the same, reference being-had to the accompanying drawings, which forma part of this specification.

My invention relates to machines for sharpening horseshoe-calks, and has for its object the providing of a simple portable and cheap of a portion of the same machine with a foot in position for sharpening the toe-calk. Fig. 3 is an enlarged detail vertical sectional View of the working portions ofthe' machine-without the sustaining framework and clearly showing its principle and modeofoperation.

In the drawings, A'represents a supporting-framework formed of two bars aa,united through a hollow standard B by bolts 1) b. The bars a a are spread, so as to form supporting or contact pointswith the floor at a a, and they are preferably united at their extremities by a wooden cross-barrin The opposite ends of the bars a a are curved downwardly and carry a traveling wheel A. Thus the whole machine rests upon three points a a and the traveling wheel Aand is easy to transport and always rests when in position on a stable foundation. The framework A is made of sufficiently-strong bars of iron or steel to give the necessary rigidity to the structure. The hollow standard B is a heavy casting, within which is adj ustably carried a compound upright 0, 'made up of several pieces. Its height can be adjusted by means of a screw S, threaded in the bottom thereof Serial No. 18,206. (No model.)

d 01, passing through the side pieces 0 c. A set-screw S is used as a means of longitudinaladj ustment of the block D. .The block D may be raised and slips passed in under it as a means of adjustment, if desired. observed that between the side pieces 0 c and at the u pperend of the compoundbar is left a inortise of peculiar shape, as shown in the sectional'Fig. 3.

proper shape to grasp and hold any conical surface inserted between the inclined lower and corrugated faces of the die D or the upper inclined cam-face of the die D. This cam is held in position between the blocks dies'D', being held therein by bolts or pins It will be Pivotedin this mortise is'a double cam-lever E, carrying cams e e of a D and D by a strong through-pin E. An arm I E extends from the cam-head E, to which is pivoted the link G. Upon the rear side of the compound bar 0 is-forn'ied a pair of brackets H, to which is pivoted a lever J by means of a pin K, This lever inay be of any reason-. able length, and to itis'pivoted at g the link G. It will be readily seen that the oscillation of the lever J will cause the jaws formed by the cam E to openand close with a drawing motion upon the part of the cam projections e e and that the combination of the levers and linkages form a compound lever of great power.

As shown in Fig. 1, the compound standard O is cut out'opposite the upper cam in or der'to facilitate the entrance of a toe-calk, as shown in Fig. 2. Pivoted upon the pin F is a leverL, having'two sides which grasp or inclose the compound standard 0 and which are formed of one piece having a peculiar shape, as shown in the drawings, the front loop M of which is adapted to grasp the toe of the hoof and hold it firmly when the toe-calk is placed in between the jaws e and D. This lever L is continued by a single piece L, forming a foot-piece L upon which the operator can outer extremities L of the lever L and holds the toe in that position, the lever J being raised when thus in position, and on depressing the lever J the call; is both drawn and compressed to any required degree ending with a sharp edge. On lifting the foot from the lever L the spring N releases the toe and the shoe is withdrawn. The heelcalk is placed between the jaws e and D, as shown in Fig. 1, when the lifting of the lever J will perform the same operation upon the calk inserted that was performed upon the toe-calk. This operation isrepeated until all the calks are sharpened as desired.

What I desire to claim is 1. In a machine for sharpening shoe-calks, a portable frame, a vertical standard carried thereby,a cam located on said standard adapted to turn in a vertical plane, means for actuating the cam, a die having its working face approximately horizontal and extending inward from the side of said standard, whereby the calks of the shoe upon the hoof may be placed against said die, said die being fashioned to cooperate with the cam and held rig-- idly by the standard whereby the oscillation of the cam opens and closes a space between the die and the cam, thereby compressing and sharpening the talk, substantially as described.

2. In a machine for sharpening shoe-calks, a portable frame, a standard carried thereby, means for adjusting the standard, a cam located in a mortise in a standard, means for actuating the cam, a die fashioned to cooperate with the cam, and held rigidly by the standard whereby the oscillation of the cam opens and closes a space between the die and the cam thereby compressing any substance inserted between them, and a lever L, pivoted to the standard and having a curved frontal portion on the short arm codperating with the standard and adapted to hold the toe of a hoof, substantially as described.

3. In a machine forsharpening shoe-calks, a tripod framework carrying an adjustable standard, a guide for said standard within which the same is adapted to move, means for adjusting the height of the standard, a double cam operated within the standard, adjustable dies formed to and cooperating with either side of the cam, means whereby said cam operates by a lever adapted to reciprocate the reverse reciprocation of the lever operating either side of the cam alternately, substantially as described.

4. In a machine for sharpening shoe-calks, a port-able frame, a standard carried thereby, a cam located upon said standard, means for actuating the cam, a die adapted to cooperate with the cam, and held rigidly by the standard whereby the oscillation of the cam opens and closes a space between the die and the cam thereby compressing any substance inserted between them, and a lever L, pivoted to the standard and having a curved frontal portion on the short arm cooperating with the standard and adapted to hold the toe of a hoof, substantially as described.

5. In a machine for sharpening shoe-calks, a portable frame, astandard carried thereby, a double cam operated within the standard, dies upon said standard adapted to cooperate one with one side of said cam to sharpen the toe-calk, and the other with the other side of said cam to sharpen the heel-calk, means whereby said cam operates by a lever adapted to reciprocate the reverse reciprocations of the lever operating either side of the cam alternately, substantially as described.

In testimony whereof I hereunto sign this specification in the presence of two witnesses.
